Application inea November 13, 1924. Sei-iai No. 749,621.

This invention relates to gages `for worle -.f;heets in a typewriti-ng machine, and oneot its obgects -is to provide convenient means lor adapting the typewriting machine Ato dil"HV ferent kin-ds ot work.

In many cases it isdesirod to type `the two [irst lines on a woiilmheet in a predetermined position relative-ly to ythe leading edge and to the sides .ot ythe sheet, and with an unusual space between said lines, as, For ere ample, -i-n typing the dateand the address in a letter.

In -order .to .locate the Worksheet so that the lirst. line may =he :typed thereon, the sheet is inserted down a paper-chute or rear table at lthe `introductory side Iot 'the yl'ilaten and is adjusted forwardly around the platen while being guided and trued by means ot the sides or side gages oit the paper-chute. Betore the lirst .line is typed, the work-sheet is 'backed up against a `loot-tom-edge gage, which may 4lee adjustably mounted, and the first lline may Aloe `typed without rfurther Vattention to `the position of the sheet.

After typing -the alirst line, the `platen rotated -w'hile the leading edge of lthe `sheet is guided up by a side gage on the delivery side of the platen, and the sheet is thus advanced' against a leading-edge gage, which may he adjustably -nfiou-nted upon a 'front gage. The second line `may now be. typed without further attention tothe location ot the sheet. Upon releasing the leading edge' of the work-sheet, the same will spring forwardly, clear of theleading-edge gage, so that new lines may he typed and line-spaced lin the usual manner.

The adjustabilit-y broadens the scope lot work `to which the machine `may be adapted. The lateral adjustment comprises two side gages which may he slidably mountedy upon the intake table.

The bottomedge gage rat the introductory siderot the platen, which controls the pos"- tion Iof the first line ot' typing, is particularly advantageous in cases where vthe first line must be placed relatively near to 'the leading edge ot the sheet. as in such cases the distance between the type of the machine and the leading ledge of the sheet is such that it will not permit the lowering of the iront gage :to `meet said leading edge.'

Certain Afeatures herein disclosed may also y side edge gage 'for the wollt-sheet, said gage being provided with a gage adjustahly ninunted thereon to and away from the platen 'to locate a `work-sheet in a line-space direction around the platen.

Another feature ofthe invention relates to an L-shaped gage-bar detachably supported on 'the platen-frame of' the typewriter carriage, said lgage-bar `having a leading-edge gage supported on `its vertical leg to position the work-sheet around the platen in a linefspace direction, and a side edge gage supported on its horizontal leg to position the work-sheet in a letter-space direction ot the platen.

Other features and advantages will'herei-na'fter appear.

In the accompanying drawings,

Figure l is .a .lront view, showing the gages, Which form the subject ot my Vinvention, applied to the platen oit a -typewriting machine.

Figure 2 it. Figure 3 is a cross-sectional view, showing the work-sheet around the platen ot a typewriting machine in a position for typing upon it thetirst line ol writing, the rear edge of the work-sheet being located against a gage at the .introductory side ot the platen. f

Figure 4 is a cross-sectional view, showing the work-sheet around .the platen of va typewriting machine in a position for typing upon it the second line of writing, the leadillustrates a work-sheet with. the vfirst and second lines of writing vtyped upon ing edge oit the work-sheet being located edge gage supported on the horizontal arm ot the L-shaped gage-bar at the delivery side oit the platen.

A. work-sheet l0 is laid flat upon a paperchute or rear table 11, laterally located by means of side guides l2, is inserted and ted around a platen 13, by means ot co-operating pressure rolls ll-fl, in the under side ot said platen, and is ted up to a position in liront ot the platen Where a type-bar l5 may strike it While being held in a typing position by a linger 16. rlhe finger-Wheel 30, tast on a shaft 3l upon which the platen 13 is niounteifl, is then turned backward and 'the worksheet backed up against a bottoni edge gage l? adjustably mounted on one ot the side guidesl i2, and theWorlt-sheet is then in a position tor typing upon it a lirst line ot typin rl`he gage 17, which forms an integral part ot a guiding meniber 18, is slidably mounted in a slot l?) in the side guides lil, and comprises a screw 2() fast to the ineniber t8, and a linger-nut 2l. for binding said gage l? in a position corresponding to the tirst line ot' typing on the work-sheet, as shown in Figures l and 3.

In order to position the work-sheet 'for a second line ot' tv ping /I, the platen is rotated While the leading edge ot the sheet is held lying' on a gage-si'ipportiug bar 22, and is ted up to a ieadingedge gage 23. The bar 92 is 'taeteneil to the machine-trame by means oiu a bracket 2li: and 'fasteners 2. rlhe gage 23 is adjustalfily mounted upon the bar 22,

" and is provided with a l'iinding screw 26 :for

readily adjusting the gage relatively to the position ot the second line ot typing on the work-sheet. The bar 22 tast on the platenlraine ot the machine at one side only, eX- tending toward the center ot the platen, and is bent uj'uvardly toi-ming a guide on which the gage Q3 n'iay be slidden.

By releasing the Work-sheet it will spring forward to a position shown in dot-anddash lines in Figure et, clearing the gage 23, and running tangentially out oit the platen 18 at the point where the finger 1G is supporting the work-sheet, and consequently the latter may be ited by means ot the regular platen feed for liiie-sinicing, and new lines may be typed upon the Worksheet.

It will he noted that means are provided whereby the gages may be adjusted ttor readily litting dittqerent classes of Work, and for Work-sheets oit' different sizes. The sideguides l2 are laterally adjustable in order that theyniay be positioned to suit the Width ot' a Work-sheet, and are mounted upon a rim 2i" t'orn'ied at the uppermost edge of the paper-chute 1l. The uppermost ends ot the guides 12 encircle the rim Q7 and torni a resilient connection rendering the side guides movable into and out oit position. The adjustment provided by the gage 17 enables the operative to loate the first line of typ- Leonesa ing on the Work-sheet, While the adjustment provided by sliding the gage 23 at the delivery side of the platen serves tor .locating the second line ot' typing'.

It Will be understood that the work-sheet may be quickly advanced to the second line by releasing the feed-rolls and then grasping the leading edge and pulling the wort:A sheet to the leading-edge gage 23, instead ol advancing the sheet by means oi the platen rotating knob.

This device may le advantageously used ll'or making entries upon certain el oi' Work-sheets in which the lli-sl, line to he typed is a predetermined distance 'troni eithe:l the bottom or the leading edge oi" the sheet. lin such eases the gages are adjusted to suit the position ot the lines on the sheets, and the entries are made by gaging the :"heels by either their bottoni or leading edges.

lt will 'further be understood that the two side guides or side edge gages l2 at the in troductory side ot the platen are comparatively long and torni a chute iTL to square the 'work-sheet. with reference to the platen. `When, however, the leading-edge gage is used and set tor a line sonic distance troni the top edge ol the work-sheet, thel bottoni edge of the Work-sheet may occupy a posi-- tion Well toward the bottom ot the chute li, and conseqi'iently there niajfv be a tendencv tor the Work-sheet to shew 'with reference to the platen, due to the short end olI the Work-sheet remaining in the chute. 'llo guard against this, however, the horizontal arm 22"- ot the L-shaped gage-bar is pro vided with a side edge gage 35 which is adjusted, in alignment with the lett-hand side edge gage l2, at the introductory side olf Vhe platen, and eo-operatcs therewith to square the work-sheet with rel'erence to the platen. Said side edge gage 35 is provided with a lateral extension or table 36 against which the Worksheet may rest when locating it against said side edge gage. Said side edge gage 35 m-ay be adjusted laterally as well as the side edge gages 'l2 at the introductoij,v side of the platen, and it may be secured in its adjusted position on said gage-bar by a thumb-screw 3i'. Y l

The L-shaped gage-bar 22 is detachahly supported on the machine, and may be readily applied to any Underwood standard typevvriting machine by means oit screws 3S, which screws ordinarily hold the cover on the end plate ot the platen-trame.

Variations may be resorted to within the scope of the invention, and portions ol.'v the in'iproven'ients may be used without others.
